Using StackPanel as ContentControl (WPF)

James McConnell picture James McConnell · Jun 1, 2009 · Viewed 11.5k times · Source

So I have a StackPanel that I am using as a ContentControl. I have a place where I want buttons to be generated based on data that I am binding to, and that is all working good, but I want the buttons to be laid out horizontally, not vertically as is what is currently happening. Here's a screenshot:

alt text

And here is the code from my ContentTemplate description:

<StackPanel Name="wpReleaseButtons" Orientation="Horizontal" Grid.Row="2">
    <ItemsControl IsTabStop="False" ItemsSource="{Binding Path=BranchCommands}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Button Tag="{Binding}" Padding="3">
                     <TextBlock Text="{Binding Path=DisplayValue}" />
                </Button>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</StackPanel>

Not sure what I'm doing wrong here. Any info would be greatly appreciated. Thanks!

I would say it looks like the ItemsControl is what is displaying the buttons vertically. if you want the buttons in the ItemsControl to be horizontal, then you need the StackPanel to be in the ItemsControl ItemsPanelTemplate, not the other way round like what you have in your code:

<ItemsControl IsTabStop="False" ItemsSource="{Binding Path=BranchCommands}">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Button Tag="{Binding}" Padding="3">
                <TextBlock Text="{Binding Path=DisplayValue}" />
            </Button>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
</ItemsControl>

I might be slightly wrong on the ItemsControl.ItemsPanel bit as I haven't got any data to test it with...
